I'm 6'1, and I usually wear a 31 waist. I like the idea of APC NS without the taper, but I'm wondering what size I should get. Do you think a 31x32 or 31x34 would be right, or should I assume that the jeans will stretch and size down to 30x32 or 30x34? Thoughts?

Can anyone explain the difference between the different APC jean styles? I'm thinking about getting a pair of raw jeans and working them in, but I'm not sure where to begin. I wear 31x32 in Levi's, but I wear them pretty low on my hips (so I could probably work with 31x33). I'm 6'1, and about 155 lbs.
Also, I'm curious -Â why are bootcuts so reviled here? I'm not quite sure how I feel about them one way or another, but I'm surprised at the level of criticism they inspire.
